nothing else.
the xt corona has lock stop on the lca. you need to cut these off. thats it. your stock tie rods and rack ends will have enough adjustment in them. if you have power steering as as well though, you might want some longer tie rods or rack ends.
you can grab the tie rods off the corona as well. theyre a 2 piece turnbuckle design, and have a greater range of adjustment, and are on car adjustable too.
if your tie rods you have on your car are new say, but your stock rack ends are fucked, just get ra60 rack ends. theyre a touch longer.
either set up will be long enough.
also xt/rt 13X are all the same.
